Additional information

1. What is NephroMAG and what is it used for

This medicinal product is for diagnostic use only.

It belongs to a group of medicines called radiopharmaceuticals.

After reconstitution and labeling with sodium pertechnetate (99mTc) solution, a radiopharmaceutical called technetium (99mTc) mertiatide is formed, which will be administered into a vein. Since the radiopharmaceutical contains a small amount of radioactivity, it can be detected from outside the body using a special medical device called a gamma camera, and an image known as a scintigram can be obtained. This scintigram will show the renal elimination of the radiopharmaceutical, providing the doctor with valuable information about the morphology and function of the kidneys and how the urinary system eliminates the radiopharmaceutical afterwards.

Doctor consultation

Discuss your symptoms and treatment with a doctor online.

2. Before using NephroMAG

Before administering this medicine, drink plenty of fluids to achieve optimal results.

Do not use NephroMAG

If you are allergic (hypersensitive) to the active substance or any of the other components of NephroMAG. If allergic symptoms, such as hives, nausea, or difficulty breathing, develop before the medical examination, the need for intervention should be considered.

  • Be careful with NephroMAG
  • When this medicine is administered to you, as it involves exposure to small amounts of radiation. Although your doctor will always consider the potential risks and benefits.
  • If you have reduced kidney function, as you may be more exposed to radiation.
  • If you are under 18 years of age, as radiation exposure is proportionally greater than in adults.

Use of other medicines:

Tell your doctor or pharmacist if you are using or have recently used any other medicines, including those obtained without a prescription.

It is not known whether technetium (99mTc) mertiatide interferes with commonly used medicines in patients who require its administration (e.g., antihypertensives or medication used to treat or prevent organ transplant rejection).

Medicine questions

Discuss your symptoms and treatment with a doctor online.

Pregnancy and breastfeeding

Consult your doctor or pharmacist before using any medicine.

If you are a woman of childbearing age (age at which you can become pregnant)you should always rule out pregnancy. If you experience a delay in your menstrual period, you should think you are pregnant until proven otherwise. In case of doubt, it is essential that radiation exposure is minimal to obtain the desired clinical information. The possibility of using alternative techniques that do not involve ionizing radiation should be considered.

If you are pregnantyou should not receive this medicine unless it is strictly necessary, as the fetus will receive a small amount of radiation, or when the benefit to you outweighs the risk to the fetus.

If you are breastfeedingyou should consider delaying the test with this medicine until you have stopped breastfeeding, and you should consider whether the most suitable radiopharmaceutical has been selected, taking into account the secretion of activity in breast milk. If administration during breastfeeding is unavoidable, breastfeeding should be discontinued for 24 hours after administration of NephroMAG, and the expressed milk should be discarded during this period. You should consider expressing milk before administration of NephroMAG and storing it for later use. It is recommended that you avoid close contact with the baby during the first 24 hours after injection to avoid transmission of radioactivity. Breastfeeding can be resumed when the level of radioactivity in breast milk does not pose a radiation dose to the child greater than 1 mSv.

Driving and using machines

No effects on the ability to drive and use machines have been described.

Important information about some of the components of NephroMAG

This medicine contains less than 1 mmol (23 mg) of sodium per dose; it is essentially "sodium-free".

3. How to use NephroMAG

This medicine should only be administered by authorized personnel who will indicate the instructions to follow at all times.

Your doctor will decide the amount of NephroMAG to be administered to you. This will be the minimum amount necessary to obtain a scintigram with the necessary quality to provide the required information.

NephroMAG is always administered into a vein.

For detailed instructions on the correct administration/use of NephroMAG, see section 6.

If you think the action of NephroMAG is too strong or too weak, tell your doctor or pharmacist.

If you are given more NephroMAG than you should

Since NephroMAG is administered by a doctor under strict control conditions, any overdose is very unlikely.

However, in case you are given an excessive dose of NephroMAG, the absorbed radiation dose should be reduced by increasing the elimination of the radiopharmaceutical from the body, for which you will be advised to empty your bladder.

In case of overdose or accidental ingestion, consult the Toxicological Information Service.

Telephone 91 5620420.

If you have any other questions about the use of this product, ask your doctor or pharmacist.

4. Possible side effects

Like all medicines, NephroMAG can have side effects, although not everyone gets them.

Very rare (in less than 1 in 10,000 patients) and mild side effects have been found: itching, eyelid inflammation, and cough. Occasionally, a mild circulatory disorder characterized by sudden dizziness or fainting has been reported.

For all patients: exposure to ionizing radiation should be justified based on the expected medical objective, obtained with the minimum possible dose of radiation received by the patient. Exposure to ionizing radiation is associated with the induction of cancer and the possibility of developing hereditary defects. However, the absorbed radiation dose is likely to be much lower than the radioactivity to which you are naturally exposed during a year in your normal environment. The probability of these reactions occurring is low due to the low doses of radiation received.

In patients with reduced kidney function:careful indication is required, as they may be more exposed to radiation.

In the pediatric population (under 18 years of age):it should be taken into account that the received dose is proportionally greater than in adults.

Reporting of side effects:

If you experience any side effects, consult your doctor or nurse, even if they are possible side effects not mentioned in this leaflet. You can also report them directly through the Spanish Pharmacovigilance System for Human Use Medicines: https://www.notificaram.es. By reporting side effects, you can help provide more information on the safety of this medicine.
